Description

Hello

Trying to compile an old application and getting this:

[mplab crash.txt](https://github.com/user-attachments/files/23103108/mplab.crash.txt)

it seems to be complaining about the definition of _Bool in stdbool.h - but I suspect this is a red herring...

I'm using

Product Version: MPLAB X IDE v6.25
Java: 1.8.0_422; OpenJDK 64-Bit Server VM 25.422-b05
Runtime: OpenJDK Runtime Environment 1.8.0_422-b05
System: Windows 11 version 10.0 running on amd64; Cp1252; en_GB (mplab)

This used to work with a much older version of the compiler.

I've tried running System File Checker without success.

Any help greatly appreciated.

Research direction

Start by reading the attached mplab.crash.txt and the report's references to _Bool in stdbool.h, using the stated MPLAB X IDE, Java, and Windows versions as the reproduction context. A useful outcome would be a reproducible diagnosis of the compiler crash or a clearly documented missing reproduction case; the issue does not name a source file or test.
